Give the User Update Information

View and Button Effects

The particular view and button effects you use are somewhat less important than providing them in the first place. The rule here is simple:

For example, when the user taps a button, it should be highlighted and perhaps click. Likewise, when the scroll buttons are used, the view being scrolled should not only scroll, but have some obvious visual effect to indicate the change (changing only the view's contents is usually too subtle). There are many different kinds of effects that you can add, from shuffling to zooming in or out. Thankfully, NTK and NewtonScript make the process of adding visual and auditory effects to views extremely easy.
